PAPER-=FEEDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 291,829, dated January 8, 1884.

' Application filed July 21, 1883. (N model.)

f0 all whom, it may concern:

Be it known that I, JAMES ARKELL, of Oanzgoharie, in the county of Montgomery and State of New York, have invented an improved feeding device adapted to machines for folding paper, to printing-presses, &c. and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying 1o drawings, making part of this specification.

My invention relates to a novel means for feeding the bag-blank in a machine for either folding and pasting up the bottom, or for printing on the side of a paper bag, or for feeding the sheet of paper in a paperfolding machine or in a printing-press (as the case may be) onto the periphery of the main earrier-drum or impressioncylinder.

Heretofore either nippers applied to the periphery of the cylinder which takes the leading end of the bag-blank or sheet of paper (as the case may be) from the feed board or tapes passing over said cylinder, and into the bite of which the leading end of the blank to be carried off was fed, have been employed for the purposes for which my novel contrivance is designed to be used; but in all such contrivances as heretofore employed, so far as I know, it has been difficult or impracticable to adjust the devices of the machine so as to effect the placement of the leading end of the blank at different points on the periphery of the cylinder, so that said blank might be caused to occupy any desired position on the carrier drum or cylinder (within certain limits) relatively to other devices designed to coact with said cylinder, and to act upon the paper blank on the. cylindersuch, for instance, as creases, pasters, folders, &c., (in a bag-bottoming machine,) or type-forms in a printingpress, or creasing or folding devices (or both) in a paper-folding machine.

I propose to provide for use on the kinds of machines referred to (and wherever else my 5 invention may be applicable) means for feeding that can be easily adjusted and set so as to effect the placement of the paper blank or sheet in any one of several given relative posists, essentially, in the combination,with the carrier-cylinder and carrier-tapes coacting with the periphery thereof, of spring-fingers or presser devices which protrude from the periphery of the cylinder, and are adapted to press and hold against the carrier-tapes the leading end of the paper blanks fed to the ma chine, said yielding fingers being adapted to be set at different points in the circumference of the carrier-drum, as the nature of the blank to be acted on and the work to be done may require, all as will be hereinafter more fully explained.

To enable those skilled in the art to make and use my invention, I will now proceed to more fully explain it, referring by letters to the accompanying drawings, which form part of this specification, and in which I have shown my invention carried out-in about the best form now known to me, and applied to a paper-bag-bottoming machine, such aspatented to me on the 26th day of December, 1871.

In the drawings, Figure l is a side view of so muelrof thebag-bottoniing machine as need be shown for the purpose of illustrating the application to such a machine of my invention. Fig. 2 is a partial vertical central scction of the same on an enlarged scale. Fig. 3 is a partial front view of the same, same scale as Fig. 2; and Fig. 4 is a detail view, in section,of one of the removable and adjustable boxes which contain the spring-feeder devices, while Fig. 5 is a detail view of a modification of my invention.

In the several figures the same part will be found designated by the same letter of reference.

A is a carrier-drum, on the periphery of which the bag-blank is placed, and on which it remains (and with which it moves) while being subjected to the actions of the creasing, folding, and pasting devices of the machine. (Not shown in the drawings.)

B is the main frame, on which are mounted, in the well-known manner, the carrier-drum A, the feed-table O, and other working parts and fixtures of the machine, and on which are also mounted the shafts of a series of tapewheels, 0, (in the case shown there are five of I00 these wheels,) around which pass the carriertapes d, that also partially encompass the periphery of the drum A, and between which and the said drum the bag-blanks are held. I have shown a bag-blank at m, Fig. 2, in broken lines, in the position in which it would be placed by the attendant of the machiue,(with its leading end shoved down against the stops 9b,) ready to be seized between the biting ends of the spring-feeder devices 0 and given parts of the under surfaces of the carrier-tape (Z. Each of the spring devices e is mounted, as shown, (see Figs. 2, 3, and4,) withina box-like device, g, which fits within and is adapted be adjusted longitudinally in an oblong recess or cavity, 71., in the periphery of the drum A, and is formed with a flange-like 6Xt611SlO11-1)l2tt0, i, on one side at its base. In the said flangelike portioni is a longitudinal slot, 7', through which passes a fastening-bolt, 7c, the head of which overlaps the edges of said slot, as shown, and which, passing through a hole in the cylinder A, is provided at its threaded end with a thumb-nut, Z, all as clearly shown. The root of the spring-feederc is secured to a cross-bar, f, of the device 9, and the latter may be moved endwise into different positions within the recess or housing 71-, and may be fastened in any given position by means of the clamping-bolt k.

In Figs. 1, 2, and 3 I have shown the carrier-drum A turned into different positions, so that the feeder devices 0 appear in different positions relatively to the feed-table and to the blank to be operated on. At Fig. 1 these feeder-fingers are shown as beneath the feed-board as the drum is turning in the direction to take on a bag-blank. At Fig. 2 they are further advanced toward the point at which they are to coact with the tapes, the blanks m (in this figure) having been fed down against the usual stops, n, while at Fig. 3 the drum is shown as having advanced or turned well past the point at which the feeders begin to eo-operate with the tapes d. It will be seen by reference to Fig. 2 that when the drum A shall have turned a little farther in the direction indicated by the arrow the feeders '6 will have their free ends brought into contact with the under surface of the bag-blank m, near the leading end of said blank, and will then, as the drum turns still farther, press the blank forcibly against the under surfaces of the carrier-tapes d, causing the blank to travel along in the bite of the said feeders and said tapes, the said feeders themselves being pressed down within their box-like devices when their free ends shall have gotten to the point where the leading end of the blank at will have become forced down fairly onto the periphery of the drum A by the action of the tapes (I. At

the point where the tapes (1 leave the drum A, and where the blank is led off from said drum, (by any suitable means,) the free ends of the feeders e, becoming again relieved of the pressure of the carrier-tapes, again spring out into their normal position, (such as shown in Figs. 1 and 2,) ready to. again act in conjunction with the carrier-tapes, to seize and carry round another blank. I have shown but one set of these feeder devices 0 on the drum A, though in practice on the bag-bottoming machine on which I have successfully practiced my invention I have employed ,two sets, arranged at about diametrically-opposite points and it will of course be understood that any number of sets of these devices may be employed on any one drum, according to the size of the latter, and to the character of the work to which the machine is adapted or that may be done on the machine.

As those who are skilled in the art well. know, 011 a bottoming-machine bag-blanks of different sizes must be placed differently on the drum A, in order to have the pasting, creasing, and folding devices all act at the proper points on the variously-sized blanks.

Suppose, now, that the machine shown be designed for use in the manufacture of Arkell& Smiths square-bottomed paper flour-sacks of three different sizes. In such case the sliding borclike devices 9 might be set in about the position shown within the recesses 71, and there clamped fast to make the middle size, while to make the largest and the smallest sizes said devices g would be shifted and secured nearer to one and the other ends of the recesses h, so as to bring the free ends of the spring-feeder devices 0 to the various and proper positions to sooner or later strike and carry off the leading end of the blank m, accordingly as thelatter might be for larger or smaller bags. Upon the same principle in a paper-folding machine or in a machine for printing bags or other articles of different sizes, or having the printed matter located farther from or nearer to the leading end of the material, blank, or article fed from the table 0, the improved feeding contrivance, composed of the spring-fingers c and the tapes coacting therewith, may be adjusted as circumstances may require.

Of course, modifications may be made in the details of construction of the novel contriva-nce without departing from the principle of my invention. For instance, I have fully contemplated and tried the use of three separate spring devices, each having a fixed position in the recess h, and all provided with pulldown clamping-screws, so that any one of the three might be used while the other two would be held with their free ends below the periphery of the drum A, and hence in an inoperative condition. (Such m'odifications seen at Fig. 5.) Such a modified form of the invention dispenses with the use of the sliding device g, and of course the employment thus of a series of springs, any one of which may be set to act, answers fully the desired ends of devices can be accomplished, which, in machines for many kinds of work, may be considered a desideratum.

Having now so fully explained my invention that those skilled in the art can understand and use it in any form in which it can be carried out and on any class of machine to which it may be with advantage applied, what I claim as new, and desire to secure by Letters Patent, is

1. I11 combination with the carrier-drum, impression-cylinder, or equivalent device of a bag-bottoming machine, a paper-folder, printing-press, or other analogous machine, and the carrier-tapes coacting with said drum or its equivalent, one or more sets of adjustable spring fingers or feeders, c, or their described equivalents, adapted to press the JAMES ARKELL.
